Sadly, as a songwriter you sooner or later finish developing your musical understanding.

A lot of ideas get re-used and made part of new songs if the first version didn't cut the mustard, and the stuff that gets left off usually contained the germ of something good but failed to reach a satisfactory state by the recording stage.

It feels like we've grown enough as musicians over the last few years to go new places, and our conceptual and compositional abilities have developed along with it, so we're pushing all the envelopes we can at the same time and it still feels like cutting edge work to us. It seems to resonate with people.

You find your preferred resolutions and harmonic intervals and what-have-yous, and then you either keep writing the same thing until everybody is as bored with your songs as you are, or you try with all your might to get out of those patterns. This is what a lot of the work is all about.

I always have problems with seeing how our new stuff relates to our old stuff - I'm better at seeing long lines in other people's music than in my own.

I think this insatiable need to get to know new music is a big part of why it has lasted so long.

We went from being thought of and talked about as "a band that plays a so-and-so style of music" (a grunge band, a stoner band, etc) to "a band that plays music with a certain sensibility or style to it". I'm not able to see quite what that is, but it's there and some people like it a lot.
